>>6128910MG Astray Red is not a bad build. The mech itself is pretty flexible and well balanced. The gigantic sword thing might be a little awkward but it's compatible with the included stand.
It is kinda pricey, depending on where you get it, and i have no idea what the RG is like, but the MG has that big-ass transforming sword thingy and has its parts big enough so even a hamhanded moron like me could build it.
it also has lots of decals.
